Some very interesting news has just landed as director Bryan Singer has revealed, via his Twitter feed, that “American Horror Story” star Evan Peters has joined the cast of the upcoming X-Men: Days of Future Past in the role of Magneto’s son, Pietro Maximoff, aka Quicksilver. The news arrives in the wake of confirmation from Joss Whedon that Quicksilver and his sister, Wanda Maximoff, the Scarlet Witch, both have roles in his script for Marvel’s The Avengers 2.

“Before he was an #Avenger,” Singer writes, “he was just a REALLY fast kid. Thrilled to say #EvanPeters is joining #XMen #DaysOfFuturePast as #Quicksilver.”

The news also arrives following confirmation this morning that Saoirse Ronan is interested in taking on the Scarlet Witch role in Marvel’s The Avengers 2. The actress is said to be the “model” for Whedon’s iteration of the character.

“We both have them,” Marvel Studios President Kevin Feige told SuperHeroHype of the character rights last summer. “There’s a specific arrangement with those two characters that would allow us to use them with ‘Avengers,’ but not discuss or reference their mutant or Magneto-related lineage. They can use them as mutants and as Magneto’s relatives, but cannot have anything to do with ‘The Avengers.'”

The film is based on the comic book storyline “Days of Future Past,” which ran in Uncanny X-Men #141 and 142 back in 1981 during Chris Claremont and John Byrne’s run and introduced the idea of an alternate future for Marvel’s mutants that grew out of the Brotherhood of Evil Mutants killing an important senator, leading to a future where all mutants are hunted by Sentinels.

Marvel’s The Avengers 2, meanwhile, is scheduled for release on May 1, 2015 and, while unconfirmed and unprecedented, the possibility does exist for potential collaboration between 20th Century Fox and Walt Disney Pictures and, while it’s hardly indicative of how he’ll be portrayed in the final film, Singer does mention Quicksilver’s Avengers connection in his tweet. Check back for details as soon as they become availlable.
